My engine wont start and i have changed the fuel pump, the fuel pump module, and the fuel rail sensor. it has started once for about 30 seconds but dies and wont start again.
View 6 RepliesI drive a 2005 F-150 XLT with a 5.4L engine in it. This problem only happens after I have been running the truck on a small trip (15-20 min), stop to get something, and then 5 min later start the truck up, and this is the feedback I get.
-Sometimes it barely cranks, idles for a second and then cuts back off.
OR
-Takes much longer than usual to crank and get's going fine.
This is the only time it happens, upon restart after driving for a short period.
I have a 2005 F150 XLT 5.4 that doesn't always start. I've been having this problem for over a year now.
Sometimes it will start, but sometimes it won't. Seems about every other, or perhaps every 3 days it just will not start. Then, if I wait a few hours, it'll start.
I've replaced the fuel pump, fuel filter, mass air flow sensor, fuel pump driver module, starter and the battery. None of this has seemed to effect it.
Lately I've found out that if I put the truck in neutral, then while cranking I go to park (going through reverse) it will start. Sometimes not on the first try, but after a few attempts it will start.
It should also be noted that when it does start, often it'll make some loud noise RIGHT before it starts up. Sounds kind of like the starter grinding. If it doesn't make the grind noise, the other thing it may do is all the lights and everything turn off for an instant (half a second) then come back on and start.
I'm really lost as to what to do. I've been thinking that it may be the transmission range sensor, but I really don't know. I don't want to keep spending money replacing random parts, in hopes of fixing it. I'm on the 3rd starter, because of all the cranking I have to do when it doesn't start.
My truck just shut down and now will not start//turn the key on it pulsates at the throttle under the hood and red security light pulsates same time.....I saw post a while back a truck had the same problem. I took the postive and neg off waited 2 hour put back on did nothing no codes come up either ......I was just driving along engine just shut down got it towed ....
View 3 Repliesi have a 2005 F150 5.4L while driving my message board bell indicated low oil pressure i pulled into the station and checked oil. i had to add about 2 qts i filled up with gas and the truck has not started since. I towed it home changed the oil, filter, oil pressure sensor and the fuel filter
when i try to start it the engine turns over normal no noises, knocking or anything out of the ordinary. It sounds like it wants to start but then acts like something is shutting the fuel pump down. I had the local mechanic tell me that the fuel pump was out. I can here the fuel pump kick on for no more than 2 seconds then shuts off. he told me it should pump for about 5 to 10 seconds. i am not convinced it is the fuel pump dont want to spend $300 on something i dont need.
is there a saftey cut off swith to the fuel pump when the low oil pressure indicator comes on? i also check the codes and its not giving any codes but i had removed the battery and replaced it and i am thinking that removed the codes?
My 2005 cranks but will not start. I spray starter fluid in throttle body and it will start but won't stay running. I've replaced the fuel pump and the fuel sender unit which is located under the spare tire. After I replaced the fuel sender unit It started and ran for about 30 seconds. It quit when the fuel line popped off the fuel pump and pushed gas all over the ground. I secured the gas line back on and now it won't start again unless I use starting fluid.
View 3 RepliesMy 05 f-150 Supercrew 5.4l, will start for a second and then die. I can sometimes feather it and rev it up, but it dies as soon as you let off. I changed the fuel filter and while we had the lines off we turned the key on and it pumped fuel but only for a few seconds. Shouldn't the pump run constantly with an open line?
View 1 RepliesI have a 2005 STX with 107,000 miles on it. When it is cold you have to turn the key on for 5 seconds twice then start it. When it is warm it will start like it always did. When the temperature outside is 60 or above you have to do the key thing about 5 times. I think it is my fuel pump...

View 2 RepliesBrought a 2006 f350 6.0 from the action and knowing it was damaged from the frame, i went ahead and brought a another f350 6.0 2005 from someone around town, the last owner is calming the truck was stole, and most of the engine was stole, and the windows where damage. ( I just wanted to buy the truck for the body so i can transfer the engine to this one! ) but instead of switching the engine, me and my dad went ahead and only put the missing parts back onto the engine....
I can tell the last owner wasn't telling the truth, and me and my dad where thinking the last owner made up his own story about the truck being stole !! I did a vin check and noting came up about having a bad history!!!!!!!!! I'm thinking something went bad in the truck, and the last owner did his own fault story... Anyways!!!
we finally put everything back in place, and the truck cranks, but does NOT start!! and also has no spark. sometimes it sounds like it does wanna start!! we check the fuel, and wires, oil, fuel filer! everything good, but the truck has no spark, and where not sure if thats the problem. and also switch out the Crank sensor. Still no luck!!
And also there is smoke when we crank. battery are good too, and even left the truck 28 hours on the wire to head up the engine!!
I put in a cold air intake in my 05 5.4l. Now truck will start up then die, the throttle doesnt seem to open up when i step on the gas. everything was working fine before I started on it.
View 4 Repliesford f 150 2005, engine wont crank over. Tried all these remedies but none of them work. [URL] .....
Here was the scenario: someone drove my truck in 4 low for a very long time.3 hrs doing over 80 km/h) When i drove the truck i could get it out of 4 low it is still in 4 low. But then the truck died on me.
The alternator pulley went on it. replaced the alternator then proceeded with the remedies from the link above.
I have an 05 f150 5.4 v8 super crew cab and I bought it for 3000 because of a cracked block. I bought a re-manufactured engine and installed it and now i have a knocking that wont go away. After I started it up it sounded beautiful for about 10 minutes and then i had a knocking start up. I have put about 30 miles on the new engine and still have the knocking. I let it sit over night and I started it up and there was no knocking so i drove about 3 miles to the gas station and by the time I got there the knocking was back. it runs fine no other issues but why do I have this knocking with a new engine.
View 9 RepliesMy dad is looking at a 2005 F150 2wd with the 4.6L V8 that a friend of his has. Its a 2wd XL, but has the cloth seats, the interior and body are excellent conditions. Its high mileage however, (210K), but the engine sounds good, but it has a miss and the check engine light is on. He took it about 6 months ago and had the oil changed, new belts and spark plugs, drove it very little and its been setting for sale for about 3 months.
When dad started it this evening, the engine was missing and the CEL light is on. His friend suggested he drive the truck for as long as he likes, (which he did today and he does like it) but I advised my dad to take it to a mechanic and have it checked out first, maybe even the dealer to have it checked out to be safe.... which he did today. He took it to a local Ford dealer today to get them to check it out they stated that it was a coil pack that is bad on the #2 cylinder.
They (dealer) also told him a bunch of other things that was "wrong" with it, but I think a lot of it was lies just to get him to get it fixed there and make money off of him. They said it needed an intake gasket (said it was leaking a little bit), they also said, battery and cables need to be cleaned, tranny service, coolant flush, etc, etc, etc.
Once outside the guy (tech) was bringing the truck out and my dad asked him the about that intake gasket and he acted like as if the dealer makes them act like things are a big deal, or saying they may not always need what they say. He told dad alot of those 4.6L's did that and it was really nothing to be concerned about, but I don't know.
I have a 95 Town Car with the 4.6L and am familiar with these cars, but I guess the 4.6L in these F150s are different beasts. I do know the plastic intakes on the 96+ models were issues.
I just purchased my first F150, 4.6L V8, 55,600 Miles. It intermittently has a rough idle and only seems to be when the engine is hot. I've had engine and tranny mechanics look it. The spark plugs have been inspected and are within an acceptable range. The throttle body has been cleaned. There are no trouble codes of any kind. What I can check next?
View 13 RepliesI have a 2005 f-150 with the 5.4 engine. Bought it new and now it has 107,000 miles on it. Recently,it would have a shudder at 65 or 75 mph then the passing gear would kick on and it worked perfectly. The warning check engine light came on,then,when it acted up it would flash intermittently. Took it in to the dealership and put it on the diagnosis machine. Said cylinders 2,3, and seven were not steady etc?? So,after he took it out and drove it he said those particular cylinder walls were scored. I put in a K-N air filter at about 50,000 miles,and he said that they do not seal properly and dust got by the filter into the intake and got into the engine and did this damage. One think he found was a bad coil on one cylinder and replaced it. And just as he said,when I got on the road home I romped on it and it cut out and the intermittent signal showed again! He said that that would happen and it did.

View 7 RepliesI have a 2005 f150 with 96,000 miles. Long story short, last August I was headed to the mountains going up a steep long hill and the engine light come on. once i was over the pass the light went off. During my 4 wheelin' trip it never came back on until I was headed home and going over another pass and then it stayed on for a couple of days. I had it checked and it was a cylinder 5 misfire. I did some research and found that replacing the coil cover might fix the problem and if not the spark plugs would need to be changed.
I changed the coil cover, problems solved... until I headed to the mountains. light came on and then eventually went off later that day. I didnt think much of it. then a few months later i was headed to the mountains again and the light came on in the same place on the steep incline hill. I. took it back to the shop, same reading. I decided it was time to replace the spark plugs anyways so I would invest. I have new plugs and everything is good however, I had no plans to go to the mountains in the near future. Now, a few months later I headed to the mountains and crossed my fingers it would not come on but it did.
I've done the research again and it seemed like the coil cover and spark plugs are usually the cause of the problem...however I have changed mine. The light is now off again. I don't understand what is triggering the problem and what is really happening and if it is safe to keep taking to the mountains with this happening. I did notice that everything was fine at 60MPH but once i hit the hill and steeped on the gas to go 65 and hit 4-5RMP that is when the check engine light came on...
2005 5.4L She would have a hard time starting before but after I replaced and fixed everything below she was running really good. Now back to sputtering, taking a long time to start and now not starting at all.
I have replaced; Fuel Pump, Fuel Filter, FPDM, Plugs and COP's, FRP Sensor, followed the power wire from the FDPM and found it corroded bad so I replaced it, also changed the ground location on the FDPM, I have checked all the wires from the FDPM to the drivers seat, checked all fuses.
I have power to FPDM and I have the diagram for the plug but how can I test (hotwire) the Fuel Pump without lowering the fuel tank? What should be the voltage coming from the FPDM plug? not sure about pin 1 & 6.
How can I test the FRP sensor? what are the specs for voltage?
Had the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. so I believe I am looking to replace the o2 sensor, if I am not mistaken.
How hard of a job is this? Ive done a decent amount of engine work and worked in a shop in high school. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if I am not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?
